It is common in the manufactureof lVfcIQliy" shoes to open the channelby presenting the sole progressively to the action of a rotary :7channel opening .tool' which lifts and turnsthe channel lip, the sole.being guided accurately in the p'roperpath by suitable channel and edgegauges. 'In one aspectthe present in- Yention consists in improvementsin meoha -r nism for directing andcontrolling the move:
